Explanation:

Cell membranes are selectively permeable. Some solutes cross the membrane freely, some cross with assistance, and others do not cross at all. A few lipophilic substances move freely across the cell membrane by passive diffusion. ... Large molecules do not cross intact cell membranes, except in certain special cases.

Do the information given and the map best describe adaptive evolution, convergent evolution, or coevolution? Explain your respon

miss Akunina [59]

Hi, the given question is incomplete, it is missing a diagram, the diagram is given in the attachment below,

Answer:

The correct answer is adaptive evolution.

Explanation:

Based on the given information, it is clear that it best illustrates the phenomenon of adaptive evolution. It is known that different species of finches exhibit an ancestor, which is common, however, all the species have shown adaptation based on the kind of food they are getting within their surroundings.

The evolutionary modifications that arise by getting adaptive to the specific environment are termed as adaptive evolution. These changes arise due to the phenomenon of natural selection, which further enhances the tendency of reproducing or survivorship after going through some of the challenges presented by the surroundings.

Which stattement best describes beaches

KiRa [710]

Hello there!

I do not know what the statements are but i will explain some characteristics of the beach to you!

Beaches are made of sand, they are along the coast, the coast is when a state (such as California) is along the beach, or the ocean, beaches also sometimes have trees, but usually when the ocean rises the ocean takes the tree into its depths. That's why sometimes you see tree trunks on the beach, but be careful sometimes if you sit on them they will cave in because of all the salt it absorved from the oceans water, sometimes you will see seagulls, seagulls like to eat the fish from the ocean, and/or the crabs that wash up on shore.

I hope this helped you!

Good luck!
